ABSTRACT
This chapter describes the process undertaken to generate initial design concepts for urban and rural rail level crossings. It demonstrates how the Cognitive Work Analysis Design Toolkit (CWA-DT) can be used to translate the outcomes of CWA and other analysis methods into a participatory design process with system stakeholders to create novel design concepts. The CWA-DT was developed to support the generation of new designs underpinned by the values and principles of sociotechnical systems theory. In the current CWA-DT application, the design criteria were drawn from the Work Domain Analysis and from sociotechnical systems theory principles. In terms of the Work Domain Analysis criteria, the values and priority measures were selected with emphasis on the safety-related values: Minimise risk, collisions, trauma, injuries, fatalities, near-miss events and road rule violations. Personas were used to encourage the development of empathy for different road user types, to enable them to better consider the user's perspective and to understand their motivations and challenges.
